Answer 2

Physical Properties of Chlorine

Chlorine is a chemical element with the symbol Cl and atomic number 17. It is a highly reactive and corrosive gas at standard temperature and pressure. Let's examine the given options and determine the correct physical properties of chlorine.

a) Gas, not reduced at normal temperature, light yellow color, pungent odor. - Chlorine is indeed a gas at normal temperature and pressure. - It does not reduce or condense into a liquid state at normal temperature. - Chlorine gas has a light yellow color. - It has a distinctive, pungent odor that is often described as similar to bleach or swimming pool water. - This description accurately represents the physical properties of chlorine gas [[1]].

b) Gas, liquefies at normal temperature under pressure, yellow-green color, suffocating odor. - Chlorine gas can be liquefied at normal temperature under pressure. - When compressed, chlorine gas condenses into a liquid state. - The liquid chlorine has a yellow-green color. - It also has a suffocating odor. - This description accurately represents the physical properties of liquid chlorine [[2]].

c) Substance capable of sublimation, black-gray with metallic luster (violet vapors), pungent odor. - Chlorine does not undergo sublimation, which is the direct transition from a solid to a gas. - Therefore, this description does not accurately represent the physical properties of chlorine.

d) Liquid, brownish-brown color, pungent, foul odor. - Chlorine is not a liquid at normal temperature and pressure. - Therefore, this description does not accurately represent the physical properties of chlorine.

Based on the given options, option b) is the correct description of the physical properties of chlorine gas.
